Help with Tile Entities

Alright, so I cannot add or remove info to my block. Here is my code:

Alright, so I cannot add or remove info to my block. Here is my code:

Block

--snip--

    expbankte = (TileEntityExpBank) par1World.getBlockTileEntity(par2, par3, par4);

    try{

    if(expbankte==null)expbankte.setWorldObj(par1World);

    if(expbankte==null)expbankte.setExpLevel(0);

    }catch(Exception e){

 

 

That's always going to throw an exception, and you use that in every function - if it's null, how can you set the world?

 

And, you could have a perfect TE, but you never actually make a new instance - it is ALWAYS going to be null. Fix your createNewTileEntity method!

could you please show me how to create the new te? that would help alot!

Edit:

Fixed it I just need to return a new TileEntityExpBank()
